About Social Media Image Sizes
Each social media platform has specific image dimension requirements for optimal display. Using the wrong size can result in cropped, stretched, or blurry images that hurt your brand presence.
Why Sizes Matter
Platforms optimize images for their layouts. An Instagram Story (1080×1920) looks very different from a LinkedIn post (1200×627). Using correct dimensions ensures your content displays as intended.
Understanding Aspect Ratios
Common ratios include 1:1 (square), 16:9 (widescreen), 9:16 (vertical/stories), and 4:5 (portrait). Our tool handles the math and cropping automatically.
Brand Consistency
When repurposing content across platforms, maintaining visual consistency is key. Generate all sizes from one source to keep your branding uniform.
